Yes—off-grid solar systems can qualify for financial incentives in Australia, primarily through the Small-scale Renewable Energy Scheme (SRES). Under this federal scheme, eligible systems receive Small-scale Technology Certificates (STCs), which reduce upfront installation costs. While most state-based programs target grid-connected systems, off-grid homes may access special grants or loan schemes, depending on their location.
Are There Any Rebates Or Incentives For Off-Grid Solar Systems In Australia?
If you live in a remote or regional part of Australia—or you’re simply looking to go energy independent—installing an off-grid solar system can be a smart move. But the upfront costs can be significant, especially when you factor in battery storage and backup generators. The good news? There are incentives available to reduce the financial burden—most notably through the Small-scale Renewable Energy Scheme (SRES). In some states and territories, additional grants, rebates, or loans may also be available to help bring off-grid solar within reach.
What are Small-scale Technology Certificates (STCs)?
STCs are government-backed certificates that represent the environmental benefit of a renewable energy system. The number of STCs your system is eligible for depends on:
- System size (measured in kW)
- Location, based on solar irradiance (e.g. Darwin vs Hobart)
- Year of installation (the scheme phases down each year until 2030)
Each STC has a market value, usually around $35–$40, and can be traded or assigned to your installer in exchange for an upfront discount—often worth thousands of dollars.
Are off-grid systems eligible for STCs?
Yes—off-grid solar systems do qualify for STCs, provided:
- The system is under 100kW
- It uses Clean Energy Council (CEC)-approved components
- It’s installed by a CEC-accredited installer
- It meets all technical and documentation requirements
Whether you’re connecting to the grid or running your own standalone system, the eligibility is the same under the SRES. Your installer usually manages the paperwork and applies the STC value as a point-of-sale rebate.
Installer Tip: STCs for off-grid systems are based on deemed electricity output, not actual grid feed-in. This means your location and system size still influence your rebate—even if you’re completely energy-independent.
How much can you save?
The savings vary, but here’s a rough guide:
- A 6.6kW off-grid solar system in regional WA or Queensland might attract 60–90 STCs, worth $2,000–$3,500+, depending on the certificate price.
- Larger off-grid setups—often required for full-time energy independence—can generate more than 100 STCs, delivering even greater rebates. Keep in mind, that the number of STCs declines each year, so early adoption brings the biggest benefit.
Are there extra rebates for going off-grid?
This is where things get regional. While most state and territory solar rebates focus on grid-connected homes, some local governments and programs do support off-grid systems, especially in remote or Indigenous communities. Examples include:
- NT Home and Business Battery Scheme – allows off-grid battery installations in eligible areas.
- Remote Power Subsidy Scheme (WA) – provides financial support for residents in remote WA replacing diesel generators with renewables.
- Community and Indigenous grants – often support larger-scale or microgrid-style off-grid solutions.
Because off-grid living is highly location-dependent, your local council, energy provider, or state government website is the best source for up-to-date regional offers.
How do you claim your STCs?
To receive your off-grid solar rebate through the SRES, follow these steps:
- Choose a CEC-accredited installer – This is essential for system eligibility.
- Use CEC-approved products – Both panels and inverters must be listed.
- Complete the installation – Your installer will calculate the eligible STCs.
- Assign STCs – Most homeowners assign them to their installer for an instant discount, but you can also sell them independently if preferred.
Are off-grid systems harder to get approved?
Off-grid systems don’t require DNSP (Distributed Network Service Provider) approval, since they aren’t connecting to the grid. This means fewer administrative hurdles—but it also puts more pressure on getting the system design right. A poorly sized off-grid system can leave you without power in extended cloudy weather, so it’s essential to work with an experienced off-grid designer who understands your daily usage patterns, climate zone, and backup requirements.
Final thoughts: Getting the best value from your off-grid setup
Installing an off-grid solar system is a big decision—but incentives like STCs can reduce your costs by thousands. While additional rebates are less common for off-grid systems, specific grants and subsidies do exist, especially in remote and regional areas. The best way to maximise your benefit is to work with a trusted, CEC-accredited installer who specialises in off-grid systems. They’ll handle the STC process for you and help identify any local opportunities.
